Is AMD's Radeon RX 5500 XT Hamstrung by VRAM and PCIe Bandwidth?

Recommended Posts

With the release of the budget RX 5500 XT, AMD started to fill out the bottom two-thirds of its product stack, bringing much-needed competition into that segment. The graphics card arrived with 4GB and 8GB variants ($169 and $199 respectively), and in our RX 5500 XT review, some titles--namely Forza Horizon 4, Battlefield V, Far Cry 5 and Shadow of the Tomb Raider--the 4GB variant performed considerably slower when running Ultra settings. The initial takeaway from this was the 4GB capacity is simply not enough for those titles, which is correct. However, there's more to it.

I have to say, I did not think about that concept. The fact that lower VRAM cards obviously have to dump data to the system RAM once the VRAM is saturated, the fact that PCI-E 4.0 offers a quicker way in which to offload to the system ram actually improves the performance of lower end VRAM cards. Seems like an obvious statement, and it is, but not being in the situation where my GPU's have been negatively effected from a lack of VRAM, you forget about these things.
